Because of the improvement of industrial level, various kinds of mechanical transmission are increasing, so the bearing type workpiece is widely used. The workpiece of the bearing class is all used for the mechanical transmission of high precision and high speed, but the direct cause of the transmission is its roughness. Whether the inner hole or outer diameter, the mechanical transmission has higher requirements for the smooth finish of the bearing. However, while improving and improving the smoothness of the...
